So, this is kinda similar to the other I helped you with:

<span>So r is the radius of the disk. The area is known and equal to 100Pi; so 

100Pi = Pi r2

Now for r: r = 10 

Circumference = 2 PI r = 20 Pi

I hope this helped!</span>

100Pi = Pi r2
 r = 10 
Circumference = 2 PI r = 20 Pi

X2 + 8x + 19 = 0 What is the equivilent that results from completing the square?
IrinaVladis [17]

Answer:

(x+4)^2+3=0

Step-by-step explanation:

Hey there!

Standard form is what this equation is in

Standard form is this: ax^2+bx+c

So order to complete the square, you need to take the b term out of the equation, divide it by two, and then square it

In this case, the b term is 8

We need to divide 8 by 2 ---> 4

Then square 4 ---> 16

So now you should add 16 to both sides

x^2+8x+16+19=16

Now you can simplify the LHS

(x+4)^2 +19=16

Now you subtract 16 from both sides

(x+4)^2+3=0

So this is as far as you can go since you cannot take the square root of a negative number
